Hello!
I have a few questions regarding the BHA-1 headphone amplifier. My questions are regarding it's preamp functionality. I already own a BHA-1 but instead of having to go through the process of modifying it by factory, I'd rather purchase another one and use it just as a preamp. My questions are:
1. is there an option to have a 'conventional' (logarithmic) volume pot rather than the standard one which is more 'tailored' towards headphone use?
2. Considering the standard gain of the BHA-1 is 14 and 20 dB for Low and High gain positions respectively, can the gain be reduced to, let's say, 12 dB and 18 dB respectively?
3. Also, is it absolutely necessary for the difference in gain between the Low and High gain positions to be 6 dB or are other values possible?
Thank you!
